In order to keep the test meaningful, some instances of query-block that
want to check whether the node still exists and would now turn up empty
must be converted to query-named-block-nodes (which also return the
protocol level node, but that shouldn't hurt).

Now that we're checking for duplicates in the reopen queue, there's no
need to force a specific order in which the queue is constructed so we
can revert 3db2bd5508.
Since both ways of constructing the queue are now valid, this patch
doesn't have any effect on the behavior of QEMU and is not strictly
necessary. However it can help us check that the fix for the reopen
queue is robust: if it stops working properly at some point, iotest

bdrv_reopen_queue_child() assumes that a BlockDriverState is never
added twice to BlockReopenQueue.
That's however not the case: commit_start() adds 'base' (and its
children) to a new reopen queue, and then 'overlay_bs' (and its
children, which include 'base') to the same queue. The effect of this
is that the first set of options is ignored and overriden by the
second.
We fixed this by swapping the order in which both BDSs were added to
the queue in 3db2bd5508. This patch
checks if a BDS is already in the reopen queue and keeps its options.

This adds the "read-only" option to the QDict. One important effect of
this change is that when a child inherits options from its parent, the
existing "read-only" mode can be preserved if it was explicitly set
previously.
This addresses scenarios like this:
[E] <- [D] <- [C] <- [B] <- [A]
In this case, if we reopen [D] with read-only=off, and later reopen
[B], then [D] will not inherit read-only=on from its parent during the
bdrv_reopen_queue_child() stage.
The BDRV_O_RDWR flag is not removed yet, but its keep in sync with the
value of the "read-only" option.

We're only doing this immediately before opening the image, but

not causing problems because none of the checked flags are modified by

If an image is opened with snapshot=on, its flags are modified by
bdrv_backing_options() and then bs->open_flags is updated accordingly.
This last step is unnecessary if we calculate the new flags before
setting bs->open_flags.
Soon we'll introduce the "read-only" option, and then we'll need to
be able to modify its value in the QDict when snapshot=on. This is
more cumbersome if bs->options is already set. This patch simplifies
that. Other than that, there are no semantic changes. Although it
might seem that bs->options can have a different value now because
it is stored after calling bdrv_backing_options(), this call doesn't
actually modify them in this scenario.
The code that sets BDRV_O_ALLOW_RDWR is also moved for the same
reason.

qcow2: Make copy_sectors() byte based
The copy_sectors() code was originally using the 'sector'
parameter for encryption, which was passed in by the caller
from the QCowL2Meta.offset field (aka the guest logical
offset).
After the change, the code is using 'cluster_offset' which
was passed in from QCow2L2Meta.alloc_offset field (aka the
host physical offset).
This would cause the data to be encrypted using an incorrect
initialization vector which will in turn cause later reads
to return garbage.
Although current qcow2 built-in encryption is blocked from
usage in the emulator, one could still hit this if writing
to the file via qemu-{img,io,nbd} commands.

Whilst according to the Zynq TRM this device covers a register region of
0x000 - 0x120. The register region is also shared with XADCIF prefix
registers at 0x100 and above. Due to how the devcfg and the xadc devices
are implemented in QEMU these are separate models with individual mmio
regions. As such the region registered by the devcfg overlaps with the
xadc when initialized in a machine model (e.g. xilinx-zynq-a9).
This patch fixes up the incorrect region size, where
XLNX_ZYNQ_DEVCFG_R_MAX is missing its '/ 4' causing it to be 0x460 in
size. As well as setting the region size to the 0x0 - 0x100 region so
that an xadc device instance can be registered in the correct region to
pair with the devcfg device instance.
Mapping with XLNX_ZYNQ_DEVCFG_R_MAX = 0x118:
dev: xlnx.ps7-dev-cfg, id ""
